Does anyone have some data showing absorption of glass as a function of wavelength in the UV-Vis range?

The researchers have used nanoparticles of iron oxide that have been treated with a special form of magnetism. Once the particles are inside the cancer cells, the cells are exposed to a magnetic field, and the nanoparticles begin to rotate in a way that causes the lysosomes to start destroying the cells.

Researchers from North Carolina State University have found a way to reduce the coercivity of nickel ferrite (NFO) thin films by as much as 80 percent by patterning the surface of the material. For devices that rely on switching current back and forth repeatedly – such as most consumer electronics – you want materials that have low coercivity, which improve device performance and use less energy.

Researchers from ETH Zurich and Empa have succeeded for the first time to produce uniform antimony nanocrystals. These nanomaterials operate with high rate and may eventually be used as alternative anode materials in future high-energy-density batteries.

Manoharan’s lab has devised a system where microcapsules are filled with a disordered solution of even smaller particles suspended in water. When the microcapsule is partly dried out, it shrinks, bringing the particles closer and closer together. Eventually the average distance between all the particles will give rise to a specific reflected color from the capsule. Shrink the capsule a bit more, and they become another color, and then another.

A team of biologists and engineers has made bionic plants that have been upgraded with an injection of nanotechnology.

Purdue makes “ultracold” molecules that look promising for quantum computing and simulation. Using lasers to cool atoms nearly to absolute zero and then gluing them together!

Awesome article that features nanoHUB and the many things that it offers to the nano community and beyond, by International Science Grid This Week.

Scientists build the thinnest possible LEDs (3 atoms thick, close to 10,000 times smaller than the thickness of human hair) to be stronger and more efficient.

“These diamond sensors combine high sensitivity with the potential for high spatial resolution, and since they operate at higher temperatures than their competitors – superconducting quantum interference device, or SQUID, magnetometers – they turn out to be good for studying high temperature superconductors,”

Using the tip of the AFM, the researchers were able to pull single chains of molecules (polymers) off a gold surface. Remarkable behavior of nearly frictionless motion was predicted by a theoretical model and has now been verified for molecules on a gold surface.

Researchers at ICFO have implemented plasmonic nano-tweezers at the extremity of a mobile optical fiber, nano-engineered with a bowtie-like gold aperture. Note that nanoHUB has a simulator for nano-scale bowtie antennae. See second link.

Ternary nanoparticles (iron and silver core) can be used in different applications, such as a contrast agent in MRI, biomagnetic sensors, hyperthermia for cancer treatment and magnetically targeted delivery and transfection.

Jayan Thomas, an assistant professor at UCF’s NanoScience Technology Center, has received a US $400 000 grant from the National Science Foundation to pursue the use of nanoprinting techniques for turning polymers into displays whose images appear in 3-D to the naked eye.

New nanogenerator takes advantage of a common piezoelectric polymer material called polyvinylidene fluoride, or PVDF. Automatically harvests energy from ambient vibrations.

University of Colorado Boulder scientists are using nanoscale pillars to impede the flow of heat more than the flow of electricity, to improve efficiency.

The Moerner group has been studying various photosynthetic antenna proteins using the single-molecule Anti-Brownian ELectrokinetic (ABEL) trap and has uncovered new states of the light harvesting complexes with different degrees of quenching.

“They hijacked that machinery and made something that looks like the lipoprotein structures and will carry siRNA straight to the liver.”

Calculate Resistance, Tunneling Magneto Resistance, Spin Torques, and Switching characteristics of a Magnetic Tunnel Junction.

Ru nanoparticles and three test reactions—CO oxidation, CO2 reduction, and styrene hydrogenation.

A team of chemists and engineers at Penn State University have placed tiny synthetic motors inside live human cells, propelled them with ultrasonic waves and steered them magnetically.
